Scientists Report Possible Dinosaur Blood Traces in 115-Million-Year-Old Bone, Stirring Debate Over Ancient Soft Tissue Preservation
A new fossil study has reignited one of paleontology’s most provocative questions: how much biological material can survive deep time? Researchers examining a 115-million-year-old dinosaur bone say they may have identified structures consistent with preserved blood components, a finding that, if confirmed, could reshape understanding of fossilization and ancient tissue survival. The claim is preliminary, but it adds fresh momentum to a field that has repeatedly challenged assumptions about what can endure in the rock record.
